41. Where an open-pit is in bedrock:

(1)  overburden shall be removed from the upper rim of the working faces and walls so that:

(a)  the cleared bench is at least 2 m wide (6.6 ft) at all times;

(b)  the land located above that bench has a slope less than its natural embankment;

(2)  undermining is prohibited;

(3)  any overhang on a face or a wall shall be stoped immediately;

(4)  no worker shall work on a working face or be located at a lower level in proximity to a working face or a wall, unless the working face or wall has been scaled beforehand of any rock likely to become detached therefrom;

(5)  if the depth of the mine exceeds 25 m (82 ft), the contours of the profile of the working faces and walls shall be determined so as to ensure their stability and drilling and blasting must be controlled so that the intended profile of the faces and walls may be maintained;

(6)  material on a berm shall not be allowed to accumulate if persons could be at a lower level near the berm.
